What is CGPA?
Understanding the CGPA System in Bangladesh
The academic journey is marked by two key metrics: GPA and CGPA.
- GPA (Grade Point Average) or SGPA (Semester Grade Point Average): This is the grade average calculated for a single, specific academic period, usually one semester. It shows your performance in that specific term.
- CGPA (Cumulative Grade Point Average): This is the overall average grade point achieved across all completed semesters of a degree program. It is the final official academic measurement used for transcripts and employment.
The entire CGPA system in Bangladesh is generally based on a credit-weighted evaluation model. This means that courses with more allocated credit hours (typically major or intensive subjects) have a larger impact on your GPA and subsequent CGPA than courses with fewer credits.

GPA & CGPA Grading System in Bangladesh
Most public and private universities in Bangladesh utilize a standardized grading structure based on a 4.0 scale for calculating GPA and CGPA. This generalized GPA grading system in Bangladesh maps a student’s numerical marks to a specific letter grade and an associated Grade Point.
Generalized Grade-to-Point Table
While minor variations exist, the following table represents the widely adopted CGPA grading system used by the majority of higher education institutions in the country.
| Numerical Equivalent (Marks) | Letter Grade | Grade Point | Remarks |
| 80% and above | A+ | 4 | Excellent |
| 75% to less than 80% | A | 3.75 | Very Good |
| 70% to less than 75% | A- | 3.5 | Very Good |
| 65% to less than 70% | B+ | 3.25 | Good |
| 60% to less than 65% | B | 3 | Good |
| 55% to less than 60% | B- | 2.75 | Satisfactory |
| 50% to less than 55% | C+ | 2.5 | Pass |
| 45% to less than 50% | C | 2.25 | Pass |
| 40% to less than 45% | D | 2 | Pass |
| Less than 40% | F | 0 | Failure |
Academic Note: Always consult your official university academic regulations for the precise GPA grading system in Bangladesh used by your institution, as some may use a straight point system (e.g., 4.0 for 80% and above, 3.0 for 70-79%, etc.).

How to Calculate CGPA (Step-by-Step Guide)
To reliably calculate CGPA and accurately predict your results, you must follow the credit-weighted calculation logic
1. The Credit-Weighted Formula
The formula ensures that the final result reflects the importance of each course based on its credit load.
This formula is used for calculating both the SGPA (for one semester) and the CGPA (cumulatively across all semesters).
2. Step-by-Step Calculation for SGPA (Example 1)
Let’s illustrate how to calculate CGPA for a single semester (SGPA).
| Course Name | Credit Hours (Ci) | Letter Grade | Grade Point (GPi) | GP × Credits (GPi×Ci) |
| Physics I | 3 | A+ | 4 | 4.00×3.0=12.00 |
| Mathematics I | 3 | B+ | 3.25 | 3.25×3.0=9.75 |
| English | 2 | A- | 3.5 | 3.50×2.0=7.00 |
| Workshop | 1.5 | B | 3 | 3.00×1.5=4.50 |
| Totals | ∑Ci=9.5 | ∑(GPi×Ci)=33.25 |
Using the formula:
3. Step-by-Step Calculation for Final CGPA (Example 2)
This example shows how to find CGPA cumulatively by combining results from two full semesters (SGPA → Final CGPA).
| Semester | SGPA Achieved | Total Credit Hours Completed in Semester (CTotal) | Total Grade Points Earned (SGPA×CTotal) |
| Semester 1 | 3.499 | 15 | 3.499×15.0=52.485 |
| Semester 2 | 3.75 | 18 | 3.750×18.0=67.500 |
| Totals | ∑CTotal=33.0 | ∑(SGPA×CTotal)=119.985 |
CGPA Calculation:
This result, 3.636, is your final CGPA after two semesters.
Semester GPA (SGPA) → Final CGPA
The final CGPA is simply the aggregated result of all SGPAs achieved throughout the program, weighted by the total credit hours attempted in each respective semester. This is the core logic applied by any effective Semester CGPA calculator.
How to calculate CGPA out of 4
The grading system in Bangladesh is inherently a 4.0 scale. When you use the credit-weighted formula, the maximum possible result is 4.00. Therefore, the calculation naturally ensures your result is computed out of 4, making the process straightforward for local and international standard referencing.
Common Mistakes Students Make
- Ignoring Credit Weighting: Simply averaging SGPAs without multiplying by the total semester credit hours will lead to an incorrect CGPA.
- Confusing GPA vs. CGPA: Mistaking a single semester result (GPA/SGPA) for the cumulative degree result (CGPA).
- Including Failed Courses Incorrectly: Always include the grade point (0.00) and credit hours of any failed course (F grade) in the calculation until it is successfully repeated and a passing grade is achieved.
How to Calculate CGPA Using the Tool
Our tool is designed for maximum speed and accuracy on any device.
- Select Your Preset (University/Program): Use the drop-down menu to select your institution (e.g., National University, Public University, Private University, or Custom). This automatically loads the correct grading scale and, where applicable, the retake logic.
- Choose Term Mode: Toggle between Semester, Trimester, or Year mode based on your program’s structure. Then, specify the total number of terms you have completed or plan to calculate (e.g., 8 semesters for a 4-year Honours degree).
- Input Credits & Grades: For each course in each term: enter the course Credit (e.g., 3.0, 4.0, or 1.5 for labs) and the Letter Grade you achieved. You must enter all credits in the denominator to get the correct weighted average. The system offers live validation and warns you if credits are missing.
- Review SGPA & Cumulative CGPA: Your SGPA for the current term and your total CGPA will update live on the sticky summary card located on the right (or at the top on mobile). Review the detailed breakdown of “Earned Points” for full transparency.

CGPA to Percentage Conversion
A common student query is the translation of CGPA into a percentage score.
Disclaimer: Most universities in Bangladesh do not officially issue a percentage equivalent on the academic transcript. The CGPA itself is the final academic metric.
However, several common (but unofficial) rules of thumb are used for external requirements, such as international applications or certain job sectors:
| Conversion Method | Formula | Notes |
| Standard Rule (Common) | Percentage = CGPA × 25 | Used widely for quick estimation. Example: 3.50×25=87.5% |
| Alternate Rule | Percentage = (CGPA × 20) + 20 | Used by some institutions in South Asia. Example: (3.50×20)+20=90% |
Crucial Academic Warning: Do not rely on these formulas for official purposes. Always clarify with the requesting organization (e.g., employer, foreign university) which conversion method they accept, or simply provide your official CGPA.
CGPA Calculator BD vs GPA Calculator BD
The names highlight the primary function:
- GPA calculator bd (or SGPA calculator) is designed specifically to calculate the result of one single semester only.
- CGPA calculator bd is designed to calculate the cumulative average over multiple semesters or the entire program.
A good CGPA Calculator should ideally function as both, allowing users to input one semester’s data for SGPA, or multiple semesters’ data for the cumulative CGPA.
Honours CGPA Calculator: Accounting for 4 Years
A typical Honours degree in Bangladesh spans four academic years, resulting in approximately 8 to 12 total semesters (including practical and thesis components).
When using an honours cgpa calculator, you need to ensure the tool allows you to input grades and credits for all completed semesters. This means calculating the total credit points earned from all 4 years and dividing them by the total attempted credit hours, according to the main formula.
Semester CGPA Calculator (Multi-Semester Input)
An advanced Semester CGPA calculator or online tool facilitates multi-semester input. Instead of calculating SGPA semester by semester and then combining them manually, the tool should allow you to:
- Input the total credits and SGPA from previously completed semesters.
- Input the current semester’s courses, grades, and credits.
- Combine all data instantly to yield the updated cumulative CGPA.
This functionality is what separates a basic GPA tool from a robust, continuous Semester CGPA calculator.

Frequently Asked Questions (FAQs) About CGPA Calculation
The fastest way is to use a dedicated CGPA Calculator tool, enter your course grades and credit hours for all completed semesters, and let the tool automatically apply the credit-weighted formula.
While most follow the 4.0 scale and credit-weighted logic, small differences exist, especially in the mark ranges for specific letter grades (e.g., 80% vs 75% for A+), and the policies regarding course retakes or failed courses.
Yes. A GPA calculator BD calculates one semester's result (SGPA), while a CGPA calculator BD calculates the overall cumulative average of all semesters completed.
The formula used to calculate CGPA out of 4 is the credit-weighted average: (GP × Credits) / ∑ (Total Credits). Since the maximum Grade Point is 4.00, the maximum result is 4.00.
There is no single official method for CGPA to percentage conversion recognized by all institutions. You should use the official CGPA and provide the conversion rule (like CGPA × 25) only if explicitly requested by a third party.
Yes, any reliable tool or method used to calculate your Honours CGPA calculator must include the grades and credit hours from all 8 to 12 semesters of your four-year program.
You combine results by multiplying each semester's SGPA by its total credit hours. Sum these Grade Points, and divide by the total cumulative credit hours attempted. This is the function of a Semester CGPA calculator.
The CGPA system discussed here primarily applies to university-level (Honours/Masters) education. Grading systems for HSC/SSC (Higher Secondary/Secondary) may differ, often using a 5.0 scale.
All credit hours for courses officially listed on your academic transcript, including any repeated courses (with the final passing grade), must be included when learning how to find CGPA.
The most important factor in the GPA grading system in Bangladesh is the credit hour of a course, as it determines the weight of that course in your final CGPA.
